NIP is c00def58 (m8xx_ide_init_hwif_ports) LR is c0002da4 (inside ide_init_hwif_ports) I gather that LR is the place you were called from and NIP is the next instruction, in which case both of these seem to be correct. mike ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
